Omori isn't for everyone, but it somehow ended up cracking into my personal top 5 games ever, so I'll say if you jive with it you're in for a really good time. Someone who's been playing indie RPGs or Earthbound-alikes for years may not be as impressed and captivated as I was. I'm looking forward to double-dipping on Switch.
The soundtrack is pretty amazing, no matter how you fall on the game. I shelled out extra on Steam for the 179-track download, and
it's on Bandcamp. Toby Fox even contributed before Undertale was released (Omori started dev in 2013). The heavy piano emphasis in the game elevated my personal experience, and I'm learning to play some of the songs myself.
I almost have this one down, just need to perfect the timing and get more consistency for rolled chords.
